The model number on 2007 models is located on left bearing hanger
Where do you look to find the numbers?
From 1996-2002 the Serial number of the chassis and the product designation numbers were located on the left
side bearing hanger where the brake caliper attaches to the kart. In recent years it has been on the same bearing
hanger only on the backside of the hanger or on the wheel side underneath the axle. A plate is often welded on to
the frame with the Birel name and a series of numbers. That is the homologation details but the chassis model
might also be listed. There are numerous other models of Birels in circulation and we can assist clients who need
more information on a case by case basis.
Basic Model Information -
Each "chassis number"
is made up of a series of letters and numbers that
will give you an idea of whether the kart was built
with or without front brakes, what "model/chassis
design" it is, what size tubing it uses and a code to
determine the year
Front brakes or Not?
"C" - If the chassis number begins with a "C" - the chassis was designed as a shifterkart or a model that has front
brakes. This "C" would be incorporated at the beginning of the model code.
Model -
The next designator will be the MODEL. For Birel, the model will either be an "R" or an "M". The difference
will be visually in the outer main frame rails. A more traditional looking, two-bend design is the "R" - a single-bend
design is the "M".
Chassis Number / Tubing Size -
After the model number will be a series of numbers. Beginning in 2000, the
numbers correlate with the size of tubing used to manufacturer the kart. (25 = 25mm tubing, 30 = 30mm tubing, 32
= 32mm, 31 = a mixture between 30mm and 32mm, etc.)
Year / Year Designator -
For the shifter drivers who want to figure out the year your kart was produced here is a list of the models by year for
the 32 mm Tube shifter karts. The year designator will be located AFTER the tubing size numbers.
